If I followed this thread sufficiently, it seems as if no one has yet
made a statement about the update of ANGLE. I just remembered that a
couple of weeks ago I came across this warning message when running
some simple fragment shader of mine:

    warning X3206: implicit truncation of vector type

Some googeling revealed that others have seen the same:


Some more revealed that it is actually an ANGLE bug that has been
fixed since last November:


According to http://qt.gitorious.org/qt/qtbase/blobs/stable/src/3rdparty/angle/src/common/version.h,
the currently shipped version in qt is 1318, while the latest upstream
version of their trunk is 2040:

I'd suggest to upgrade ANGLE to something after the mentioned fix, but
since I don't see any 'proper' released upstream version other than a
very old 'v1.0' branch, I would not know which version would be suited
best. How has the currently used version been chosen at the time?

P.S. this is not necessarily an offer to do the upgrade myself (I
don't even have enough space to build qt on my windows partition right
now) but I might be convinced to do so if no one else feels
'responsible' for ANGLE.
